Hardware The hardware are the parts of computer itself including the Central Processing Unit CPU and related microchips and micro-circuitry, keyboards, monitors, case and drives floppy, hard, CD, DVD, optical, tape, etc Expansion buses establish links with peripheral devices.

Also called the processor or microprocessor. CPUs contains a variety of circuitry and components and are connected to the motherboard. Random Access Memory or RAM is the memory that the computer uses to temporarily store the information as it is being processed.
